Does filling basins up with freshwater count as /tech/? I mean it's all there, engineering, math, science, construction, hydroelectricity, irrigation...

I love you Shaytan, never stop posting
Interesting, are you an engineer or scientist of some kind ?
>>3848 I'm just a retard who likes rain and a steady supply of freshwater to keep the plants alive. The world of Mad Max doesn't appeal to me
http://riverbasins.wateractionhub.org https://www.floodmap.net https://en.wikipedia.org/wiki/Tarim_Basin https://en.wikipedia.org/wiki/Great_Basin In order to fill some of these basins up without the use of much irrigation, we would have to mass produce these to stop evaporation: en.wikipedia.org/wiki/Shade_balls These would likely be used to grow the size of Lake Chad to fill larger portions of the Chad Basin. They would also be employed in the Lake Eyre basin, Tarim basin if China wanted watery Sinkiang, The Salton Sea, and Death Valley to fill the valley with water.
>>3851 I have an idea you might love. Get this: Canal going into a volcano
>>3858 Why tho
>>3859 To make more rain
>>3860 Thats actually a good idea. I love rain.
>>3860 >>3861 and the volcano would clear the water of impurities maybe
>>3858 >>3860 won't work.it will destroy the canal and overflow it can cause more problem than benefit

>>3897 https://en.wikipedia.org/wiki/Endorheic_basin >An endorheic basin (/ˌɛndoʊˈriː.ɪk/; also spelled endoreic basin or endorreic basin) is a drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but converges instead into lakes or swamps, permanent or seasonal, that equilibrate through evaporation. They are also called closed or terminal basins or internal drainage systems or basins. Endorheic regions contrast with exorheic regions.[1] Endorheic water bodies include some of the largest lakes in the world, such as the Caspian Sea, the world's largest saline inland sea.[2] >Basins with subsurface outflows which eventually lead to the ocean are generally not considered endorheic;[3][4][5] they are cryptorheic.[6] >Endorheic basins constitute local base levels, defining a limit of erosion and deposition processes of nearby areas.[7]

>>3926 >the balls have a lifespan of ten years, and the plastic may be reused after that.[9] https://en.wikipedia.org/wiki/Shade_balls >But a team from the Massachusetts Institute of Technology, Imperial College London and University of Twente in the Netherlands reported Monday that it may take more water to make the shade balls than what they save. To offset this loss, the shade balls must sit on the Los Angeles Reservoir between 1 to 2.5 years. https://www.pbs.org/newshour/science/why-96-million-plastic-shade-balls-dumped-into-the-la-reservoir-may-not-save-water

How would you fill these basins? The most logical ones to fill would be the ones in regions with serious desertification.

>>3971 That's my thoughts as well. Nobody cares about a stupid desert so they'd be the best ones to fill. The biggest thing would be to create inward flow from either pre-existing rivers or canal projects from elsewhere, and to prevent evaporation to allow water to collect and increase the size of lakes in those regions. Chad basin is an endorheic basin, it's huge, but the lake inside is about 1/10th, 1/15th the surface area of the basin proper. Probably the best thing to do would be to cover the entire surface of the lake with shade balls, preferably just before a rainstorm, that way the lake will increase in size allowing any life living inside the water to be able to acquire sunlight in some areas where the sun will still be present, meanwhile the majority of the lake will be covered in anti-evaporation devices which will increase the size of the lake until the next rainstorm, at which point more shade balls will be added just beforehand to further increase the size of the lake gradually. As for cryptorheic basins such as San Joaquin, these basins have rivers constantly outflowing into the oceans, so it's as simple as damming it up and letting water collect. As for basins where no substantial bodies of water are present, such as Fezzan Basin, I'm not certain. I imagine water would have to be diverted from elsewhere, but as to where such water would be acquired i have no idea. It's obviously higher in altitude than the mediterranean sea and chad basin. Some combination of damming to prevent rain from escaping certain areas alongside anti-evaporation measures would make it hold enough water to expand in certain areas making the entire basin more wet as a result, at which point it's only a matter of time before the lake grows to full size.
>>3973 I have combined a few things that could be cheaper and less manpower intensive, along with less side unintended effects downstream from diverted rivers. The Keystone Pipeline in America can shift 110,000 m3/d of oil a day (may be more for something like water), it also spans north to south of the country. From a quick glance the network appears to have cost $12b https://en.wikipedia.org/wiki/Keystone_Pipeline https://en.wikipedia.org/wiki/List_of_oil_pipelines Every cubic metre of water is 1000 litres. One of the largest desalination plants in the world is Ras Al Khair, Saudi Arabia: 1,036,000 m3/day (Israel has the largest apparently but this is way over requirements so I didn't bother looking) Ras Abu Fontas (RAF) A2 – 160,000 m3/day is closer to requirements, and the plants typically cost $1.8b https://en.wikipedia.org/wiki/Ras_Abu_Fontas#Desalination_plants So we can get 110km3/d, assuming the world's largest pipeline is the limiting factor That is the size of Lake Nicaragua https://en.wikipedia.org/wiki/Lake_Nicaragua https://en.wikipedia.org/wiki/List_of_lakes_by_volume So really it's overspecced even for this, but I'm not sure what the major costs of pipelines are, whether it's the length, capacity, pumps, or local labour prices. Interesting sidenote is that some of these large oil pipelines going by bodies of water are part of a long running conspiracy theory that Big Oil intends to monopolise water in America in the future
>>3974 Sorry I forgot to add that the logic here is pumping water directly from the sea and desalinating it.
/tech/ is for technology or more specifically computer hardware and software. This thread belongs in hobby or edu.

>>3971 I would just cut a channel directly from the Gulf of Mexico and fill the parts that are below sea level.
I remember an episode of the old Thunderbirds puppet tv program and one of the episodes was about giant nuclear plants in africa and australia that basically did this. Because of that I think this is a really cool idea and really hope it happens.
>>3970 >Sichuan Basin Over a hundred million people live there. Something like this should be limited to deserts.
>>4124 No amount of people is too much. That's one of the reasons a housing guarantee is one of my personal favorite goals, because if you wanna do a project like this you'd want to be able to easily relocate people and ensure their needs are met without worrying about finance very much. I do agree, however, that sichuan basin wouldn't be a high priority. Tarim, jungar, qadam, and uvs nuur plus hyargas nuur, being in the middle of a desert, would be a better location, although i worry about the effect that would have on belt and road, for example, located in sinkiang.
>>4094 That's the gulf of california, and i believe the canal there would be better going northwest to fill that basin then northeast to fill salton completely
>>4136 >gulf of california That's what I meant. Yeah the purple line is where I would cut canals.

>>4294 Yeah and it's full of plants and animals that already thrive there. Maybe don't obliterate them with a geoengineering project whose consequences you can't fully grasp?
>>3974 Your math is off. 110,000 m3/d is not 110 km3/d. It's only 110 ML, which is enough to grow 22 ha of vegetables or 10 ha of rice for a season.

Can mods move this thread to either >>>/hobby/ or >>>/edu/, depending on where it fits best? I think it would be better off on one of them.
